Actually I have changed my mind since initially seeing the incident. What was Perez doing defending with only front brakes? Massa left no margin for error, but this doesn't excuse Perez moving around in the braking area. It wasn't even a serious attempt to move to the left hand side of the circuit - inexcusable really.

For me, Perez moved in the braking zone. Otherwise there would have been no contact. It's something the stewards ought to look at because moving in the braking zone is hevily frowned upon and this accident is a textbook illustration of why.

Perez. He triangled way too much the braking zone, which is especially stupid with damaged brakes as the other car will always brake much later. If he wanted the inside, he should have defended earlier. He should have picked a side and commit to it, he changed his mind too late.

Ok, i have seen the replay on sky, it's Perez fault. He have made a move on the left while Massa was already there, after that move, it was impossible to avoid the crash. But it was a hard race, Perez had no brake, we shouldn't blame him.

From Perez in car it was clear he did not move towards Massa. Steering wheel straight until impact. One could claim he could have gone more right, but you can not demand from someone that they open the door at the last lap. Desperate move by Massa and entirely his fault.

Normally this is a solid argument, but the racing line is not a straight line going into turn one at Canada. Why is this different to defending in a "normal" straight braking area by turning?

Perez's fault IMO, he moved left too late to cover for the overtake just at the same time Massa had already started the move. Disappointing as it would have been a good haul of points for both drivers.

It's why it is his fault. There is a slight right hander before the braking zone, Perez with keeping his steering wheel straight was on the left while Massa was already there.

I wonder if Williams had told Massa that Perez had bad brakes, if so, that does tip it a little bit against him. But still, Perez straightening the wheel as though he was going to peek down inside of Vettel was not good.

Although I dont think he "turned left" as others say. Its more that he didnt follow the curve to the right as much as he should have done... see for example Vettel in front of him who stays right to the track edge.

Massa did the same thing he has done when trying to overtake Vettel for the past few laps. Sadly, now it was a car that had no brakes and i'm guess Massa wasn't informed about it. Also Perez was trying to defend it, but not by turning the wheel,by going straight when the track curved to the right. Compare his trajectory with Vettels'. Calling it a racing incident.

"Should have done"? Should he also have radioed in "Tell Massa he can pass left"?
